Full disclosure, I am officially a senior citizen but I don't feel my chronological age. Thanks to a regular yoga practice I am fit and flexible and enjoy a very active retirement--kayaking, hiking and cross country skiing. My body, just like yours, keeps score. I have osteoporosis and cranky joints but I am usually first through the rapids and down the ski hill. I may be bringing up the rear on steep hills but I am out there with confidence thanks to yoga.
I practice yoga with people of all ages, body types and sizes. You can adapt yoga to fit you, not the other way around. Yoga is not about contorting your body into a pretzel, it's not a competition, it's about moving and breathing. It's about quieting your mind so you can listen to your body. It's about finding stability and ease and balance.
People tell me all the time they would like to try yoga but they are too something--too stiff, too tired, too busy, etc. Try listening to your body, I think it's trying to tell you to come to yoga. Stop listening to the voices in your head that don't see you as a yoga person, your head is full of stuff that doesn't make sense. Listen to your body and come practice with me and find out what yoga can do for you.
